This is untested. How to deal with weather? I don't want a complicated table, and I don't want to roll too often--like less than three times per day of travel, and averaging close to once per day. This table is what I'm thinking about: 1-8 Calm (sunny day or clear night) 9-14 Partly cloudy 15-20 Cloudy 21-26 Precipitating (rain, snow) 27-30 Turbulent (thunder, hail, fierce winds) Method : Roll 1d6: If it's even, subtract the value if it's odd, add the value. The table bottoms out at 1, and is capped at 30. If there's a transition to a new kind of weather, roll again in 1d6 turns. Otherwise roll again in 1d6 x 8 hours, unless the value is over 20, then roll in 1d3 hours. Why? : Weather goes for days at a time in a more or less steady state. If there is precipitation, it's preceded by clouds. Precipitation can last a while, but sometimes it only happens briefly (roll in 1d6 turns), then it's gone. But how do you deal with some...
